Small CSS / Javascript job

Four relatively small CSS / Jscript jobs. Please only consider if you know CSS well - in which case it should take about 30-45 minutes to fix and I would be prepared to pay accordingly for it. Once this is complete I may have another CSS job for the site that is a little bigger. Site: [login to view URL] What is required: 1) Make the site show up correctly in IE6. Currently it looks different than more modern browsers. 2) Make the following changes to the Share button (bottom right corner): 1) Make the menu hover upward 2) Move it closer to the Share link (it's too far left now, padding is set too high) 3) Make the Share link underlined The description of how the button was created is located here: [login to view URL]­help/toolbox section Custom Hover Menu. 3) The call-back user form shows up than disappears when site is first opened. I need to make it hidden so that the user doesn't see it when first coming to the site. 4) The site shows up as having "high-risk mixed content, such as JavaScript, on the page or when the site presents an invalid certificate. " [login to view URL] I don't know which component is causing it and I need to have it fixed.
